Definitions

  • the present invention relates to methods of managing communications with a Near Field Communication (NFC) controller. It relates particularly to methods of managing communications with a NFC controller in a NFC device which is able to emulate several contactless cards.
  • NFC Near Field Communication
  • the NFC (Near Field Communication) technology is based on the exchanging of data via a magnetic field.
  • a NFC device may work according to three modes: card emulation mode, reader mode and Peer-To-Peer mode.
  • card emulation mode the NFC device behaves like an existing contactless card.
  • reader mode the NFC device has an antenna which is able to modulate the magnetic field and to provide energy to other NFC devices.
  • the NFC device in reader mode is usually named a PCD (Proximity Coupling Device).
  • P2P Peer-To-Peer
  • a NFC device may be a PICC (Proximity Integrated Circuit Card or Proximity Card) or may embed components which act as logical PICC.
  • the PICC and the PCD communicate thanks to an inductive coupling in a field frequency equal to 13.56 MHz.
  • the ISO14443 and ISO18092 standards provide modulation technologies and communication protocols which may be used in NFC domain.
  • the determinist method is defined in the part 3 of the ISO14443 standard and is mainly used for products compliant with the ISO14443-A type.
  • the statistical method is defined in the part 3 of the ISO14443 standard and is mainly used for products compliant with the ISO14443-B type or ISO18092.
